Unless you really look closely at the image above, you might not realize you aren’t looking at a normal Game Boy Advance; which is sort of the point. Even though it retains the looks of the iconic Nintendo handheld, this version built by [Akira] is supersized for adult hands. How big is it? To give you an idea, that screen is 5 inches, compared to the 2.9 inch screen the original sported.

Unlike most of the portable gaming hacks we’ve covered recently, this big-boy GBA isn’t powered by a Raspberry Pi. Internally it’s packing a genuine GBA motherboard, which has been wired into a portable screen originally intended for the PlayStation.

Though that may be understating things a bit, as getting the round PCB of the original screen into the rectangular shape of the GBA meant it had to be cut down and the traces recreated with jumper wires. The original CCFL backlight of the screen had to go in the name of battery life, and in its place is the backlight system pulled from a Nintendo DSi XL.

But where did [Akira] get a giant GBA case to begin with? No, it isn’t 3D printed. It’s actually a hard carrying case that was sold for the GBA. The carrying case obviously didn’t have a cartridge slot or openings for buttons, so those sections were grafted from a donor GBA case. So despite the system overall being so much bigger than the original, the D-Pad, face buttons, and cartridge slot on the back are at normal GBA scale.

The GBA XL is really a labor of love; browsing through the build log you can see that [Akira] actually started the project back in 2014, but it kept getting shelved until more research could be done on how to pack all the desired features into the final device.

While this may be the most historically accurate attempt at making a bigger Game Boy, it certainly isn’t the first. There seems to be a fascination with turning the quintessential pocket game system into something that’s quite the opposite.
